LAMP HOLDER FOR MINEBS' GAPS.

Application filed August 6,- 19 24. Serial no. 730,450.

To all whomz't may concern:

Be it knownthat I, LOUIS Sormnz, a citizen of the United States,residing at Wilkes- Barre, in the county of Luzerne and State ofennsylvania, have invented certain newand useful Improvements in LampHolders for Miners Caps, of which the following is a specification.

This invention relates to improvements in lamp supports for miners caps.

One of the objects of the present invention is to provide a lamp supportso constructed that lateral tilting or swinging movement of the lamp ispositively prevented.

One of the disadvantages possessed by the ordinary lamp holder of thistype is that the hook of the ordinary lamp is so loosely connected withthe support that when the head is tiltedforwardly to any considerabledegree, the lam is liable to become separated from the ho der.Therefore, it is another equally important object of the present in;vention to provide a holder having means for engagement b the hook ofthe lamp,

so constructed and located as to preclude any accidental disengagementof the lamp hook from the holder regardless of the angle to which thehead may be tilted, and likewise regardless of the direction in which itmay be tilted, so that readjustments of the lamp from time to time arenot required as in the majority of lamp holders of this class.

In the drawings:

Fi re 1 is a vertical front to rear sectiona view through the holderembodying the invention, the cap to which the holder is applied, and thelamp which is supported by the holder, being shown in elevation;

Figure 2 is a rear elevation of the holder removed from the cap;

Figure 3 is a topplan view ofthe holder, the device embodying theinvention being shown in dotted lines therei'n.

In the drawings, the numeral. 1 indicates in general an ordinary minerscap having the usual crown 2 and visor 3. The lamp is indicated by thenumeral 4 and is provided with the usual hook 5 which is united theretoin any suitable manner at the rear side of the-Water chamber of the lampand has an upwardly extending shank portion 6, an

. intermediate arcuate connecting portion 7,

and a substantially straight downwardly ex tending hill 8. The lampholder is indicated in general by the numeral 9 and the same may be madefrom a sheet metal blank having strai ht side margins and so formed asto provi e a central portion 10 which extends perpendicularly in frontof the crown 2 of the cap, a portion 11 which extends upwardly andrearwardly from the upper end of the portion 10 and-is secured in theusual, manner, as at 12, to-the top of the crown at the front thereof,and a portion 13 which extends downwardly and forwardly from the lowerend of the portion 10 and rests upon the visor 3 of the cap.

A plate 14 is riveted or otherwise secured upon the upper side of theportion 11 of the supporting member9 and is provided with a channel 15which extends in a front to rear direction and in the bottom wall ofwhich channel there is formed an opening indi- '-cated,by the numeral16. The channel 15 is formed by. stamping the intermediate portion ofthe plate 14, and the said channel extends through or depends through aslot 17 which is formed in the said portion 11 of the supporting member9, the portion 10 being likewise formed with a slot 18which constitutesa continuation of the forward end of the slot 17 as clearly shown inFigures 1 and .2 of the drawings.

As thus far described, the structure is old and well known upon themarket. In ordinary practice the book 5 of the lamp 4 is engaged withthe holder by having its bill 8 inserted through the opening 16 inbottom of the channel 15, the curved connecting portion 7 of the hookresting in the said channel 15. However, this construction is I such aone as to prevent the disadvantages which have been pointed out above,namely that the hook has merely a loose engagement with the holder andany tilting movement of the head toward either side will permit of thelamp swinging toward that side. Any

tilting movement in a forward direction, of I the head, will ordinarilyresult in the lamp becoming entirely disengaged from the holder anddropping therefrom or," in the forward tilting movement of the head, thelamp will simply pivot upon the hook and will not be suspended in theproper position. Theoretically the shank 6 of the hook is intended. toengage in the slot 18 to prevent any side swinging or tilting of thelamp,.but-actually this is not the case as is well recognized by minerswho employ holders of this type. In View of these facts, the presentinvention con-templates the pro-' vision of means, in combination withsuch a holder, for positivel preventing any side swinging or tilting othe lamp or aforward swinging thereof or disengagement of the hook ofthe lamp from the holder, thereby overcoming the disadvantages of thepresent holder. 7

The means just referred. to comprises a socket member which is indicatedin general by the numeral 19 and which comprises an attaching base 20preferably of theoblon rectangular form shown in Figure 2 which base isriveted or otherwise secured as indicated by the numeral 21, upon therear face of the portion at' the upper end thereof and immediatelybeneath the. forward end of the portion 11 of the supporting member9.The numeral 22 indicates a vertically dis osed neck which forms anintegral part withthe rear side of the attaching base and is of thesame'helght as the sald base and projects rearwardly therefrom as bestshown in Figures 1 and 2 of the drawings. A sleeve-like socket member 23is integrall formed at the rear end of the neck 22 an is ofapproximately cylindrical form and provided with an axially extendingbore 24 which constitutes a socket to. receive the bill 8 of the hook 5,the upper end of the bore bein preferably slightly forwardly flared asin mated by the numeral 25 so as to permit of more read insertion of theextremity of the bill into t e said end of the bore or socket. Byreference to F igure 1 of the drawings it will be observed that thesocket is substantially in alinement with the opening 16 and at thispoint it will be evident that when the bill of the hook is insertedthrough the opening 16' and into the socket 24 with the curvedintermediate portion 7 of the hook seating in the channel 15, the lampis positively precluded from swinging toward either side or having anylateral tilting movement. Furthermore, due to the engagement of the billof the hookthrough the said opening 16 and in the socket 24,

there can be no swinging or pivotal movement of the hook about thesupporting memher and consequently there can beho swinging or'tiltingmovement of the lamp. Furthermore there can be no accidental disengaement of the hook of the lamp from the hohler by reason of the fact thatthe member 9 being'of sheet metal, possesses a greater or less degree ofresiliency and the parts will be so arranged, as best illustrated inFigure 1 of the drawings, that after the extremity of the hill 8 of thehook 5 has been inserted through the opening 16, the bill of the hookwill engage the flared portion of the wall of the socket 24 and the saidbill of the hook, being likewise resilient, will be sprun rearwardly. atthe time it is further inserted into the socket. In other words, whilethe socket and the opening 16 are substantially in vertical alinement asabove pointed out, there is just sufficient relative displacement of thetwo on a vertical line to insure of this rearward springing of the billof the hook and a tight frictional fit of the said bill in the socket,it being observed that on account of this manner of engaging the partswith each other, it is only necessary to forwardly flare the upper endof the said socket 24. Referring again to the statement heretofore madethat the opening 16 and the socket 24 are approximately in verticalalinement, this statement is not intended to mean that the center of theopening 16 and the axis of the socket or bore 24 are in alinementperpendicularly for while the opening 16 is located opposite the upperend of the socket it is slightly displaced in aforward'direction so asto, more strictly speaking, lie immediately above the forwardly flaredportion 25 of the wall of the socket thus insuring of the frictionalbinding of the bill of the hook in the socket as previously explained.

Having thus described the invention, what is claimed as new is:

1. A lamp holder fomminers caps comprising, in combination, asupporting. member for attachment to the cap and including an uprightportion and a portion extending rearwardly from the upper end of theupright portion and having an openin there.-

in, of a socket member secured to t e rear side of the upright portionof the supporting member and provided with a socket opening, the firstmentioned openin being slightly displaced with relation to t c axis ofthe socket openin and'glocated above the upper end of the saisocket-opening, whereby to effect a springing of the bill of a lam hookinserted through the first mention opening and into the socket openingand thus cause frictional binding of the hook bill in the socketopening.

2. A lamp holder for miners caps comprising, in combination, asupporting member for attachment to the cap and including an uprightportion and a portion extending rearwardly from the upper end of theupright portion and having an openin therein, of a socket member securedto t e rear side of the upright portion ofthe supporting member andprovided with a socket opening, the first mentioned openin beingslightly displaced with relation to t e axis of the socket opening andlocated above the upper end of the said socket opening, whereby toeffect a springing of the bill of a lamp hook inserted through the firstmentioned 0 ning and into the socket opening and tlii ls causefrictional bindin of the hook bill in the socket opening, t e wall ofthe I socket opening at and adjacent the upper end of t esaid openingbeing flared in the eneral direction of the dis lacement of the rstmentioned opening with relation to the axisof the socket opening wherebythe ex tremity of the hook bill, after engagement ,10 through the firstmentioned opening, will engage and be guided by the said flare of thesocket opening, in entering the said opening.
